First off, I like this shot just as it is, as with most of your work. But if we're going to speculate as to what might work even better, I guess I'll say that maybe just darkening everything in the upper half of the shot might be effective to emphasize the main subject. But without seeing that tried, I don't know if I'd like it better or not. the main flower is much brighter and sharper already, so this might even be a matter of monitor calibration for me.
I like this Peter, but I am being a bit distracted by that one brighter daisy on the right line of thirds, hanging off the very top of the image. If that was burned down a bit so it did not compete with the main subject daisy, it would improve the image, which is a nice shot. ~ Lonnit
